Book excerpt: "Tim Worstall, always clear thinking, nails the myths that grow up around economics in this useful book. A terrific compendium of fallacies and their refutations." Matt Ridley, author of the Rational Optimist. This book is simply a discussion of those errors which I've had to repeatedly correct in this past decade of my writing about matters economic. It gets rather boring having to point out the same errors again and again: thus putting the explanations into one simple format handy for waving at people rather than having to trot out the same old explanation again. This book is an idiosyncratic look at a number of common economic fallacies and mistakes. It does not pretend to be be exhaustive, a thorough examination of all the mistakes that economics, both folk and formal, can become prey to. Rather, it's about those that I've come across and find that I have to continually point out the folly of. For example, the Labour Theory of Value has been around for a long time and forms the heart of the basic underpinnings of Marxism. Yet it was disproved at around the time that Marx was publishing Das Kapital: and it has remained wrong since then whatever the insistences of the ideologues. So there is a simple explanation of why that particular theory is wrong. On what is perhaps more my side of the fence, free market zealotry (and I confess to being a market zealot) it is also wrong to proclaim that free markets can and will solve every problem. This is not, sadly, so: there are times when interventions must be made, even times when something must be done and government is the only actor able to do that thing.
